I met Shom very briefly as he was about to board a train at Penn Station.
Aside from shoulder pieces and Sanskrit text circling his upper left arm, he has a couple of other tattoos, including this one on his inner left forearm:
This piece represents one of the many chakra for meditation.
It was inked at Jinx Proof Tattoo in Washington, D.C. Work from that shop has appeared previously here.
Shom had to board his train before I could get more information, but I express sincere thanks for his brief participation here on Tattoosday!
